Will we do such a trip again? Hopefully yes. But we will change the daily Km’s. We did almost 5.500 in total. Going into Portugal we took a week, but that was over 3.300 (including local drives). So still a lot per day. But the drive back, 2.200 in < 3,5 days is not that nice …. as I am the only driver (Jibbe does not) and there is so much to see on which we missed out.
BTW Loved going through Spain, especially near the Pyrenees and from Burgos to the coast. In Portugal a lot to like, but driving through the north, needs many to be discovered, especially near the Tua river.
Now planning the next, most probably the summer one (7.000+ Km), to the North Cape. And yes we will take ample time, 5-6 weeks.
